How to make ECU BENCH for E46 DMES & EWS for out of car programming

I know you need a 12 V Power, I have OBD2 CABLES from cars. What Pin outs do you use?

I've done the same for e36... just find a wiring diagram, there are likely several +12v and grounds you need to connect as well as the K line. Not sure if there is a separate "programming line" that needs 12v like there is on MS41.
